Structure, vibrating device, and sensory acoustic apparatus

Abstract

A structureaccording to an embodiment of the present disclosure includes: a vibration partconfigured to hold a vibrating member; a housingconfigured to at least partially house the vibration part; and supporting partsSR,SL configured to support the vibration partby coupling the vibration partand the housing, wherein the supporting partsSR,SL are each configured to have a dynamic stiffness that amplifies or attenuates transmission of a vibration of at least a predetermined frequency in vibrations generated in at least one direction by the vibration partin a state of holding the vibrating member, and a static stiffness required for supporting the vibration partin the state of holding the vibrating member. A system including the structureand the vibrating member has characteristics in which a vibration transmittance gradually decreases, as a vibration frequency of the vibration in the at least one direction increases, after exhibiting an excited vibration mode in which the vibration transmittance is increased. The supporting partsSR,SL have the dynamic stiffness that exhibits the excited vibration mode such that the vibration transmittance at the predetermined frequency is greater or smaller than 1.
